Flashing while searching for parking space???

hi leude, first of all I want to note that I actually NEVER blink (unless someone is driving behind me, which I could endanger by my turn or when leaving a roundabout…). but today I almost got a fit!! in the city on a normal road 50km/h are allowed on both sides of the road are squares and there is opposite traffic (each a track for me and one for the incoming traffic). so a normal day… however. the tip suddenly slows down in front of me abruptly and stops. in front of him no human soul on the road. since opposite traffic is I can drive by net so I have to wait… I think what does the guy want?? (he has no blinker or so) then he rolls times 5 cm forward times 10 forwards. well and I wait.. so a gap in the opposite traffic was driving the tip off and stands on the opposite track however still in the same driving direction (still without blinker) of the opposite traffic ha t is also hugely happy*g*…and in the rear mirror I see how he tries to drive backwards into a parking space on the left side of the street “empty”. I drive around the next corner and the same game again one is standing in front of me and stops again without blinking to drive into a parking lot… well that happened to me until home 4 more times! wanted to ask you if I also does this as described above just stop without blinking and into a parking platform z to drive??? or if I am also the opinion (like me), that if you are looking for a parking space (that should happen) you should at least signal to the behindman by blinking what you have in front of it! I would have as well as so afraid that if I behave as described the next one drives on it and I still get a partial debt… gruss murcielago ps am curious as you think about it and I just had to get rid of it…
